Multifilament Nb3Sn conductors

Abstract
The superconducting and mechanical properties of multifilament Nb3Sn wires prepared by the surface diffusion technique are described. Materials tested were 0.021‐ and 0.051‐cm‐diam wires with 392 filaments 6.6 or 16 μ in diameter. Electron microprobe and scanning electron microscope studies of Nb3Sn layer thickness and matrix contamination have been carried out also.
